Boiling dryer are formed using the heating of the air through the heat exchanger, hot air distribution by the valve plate into the host, the wet material from the feeder into the dryer, because of the role of wind pressure, the material formed in the dryer with a boiling state, and with the hot air extensive contact drying materials to be completed in a relatively short time. Powder Granulating, improve mobility, reduce dust; through the the powder granulation improve its solubility; mixing, granulation, drying step granulation in a machine; antistatic filter cloth, equipment operation safety; boiling Dryer
Set the pressure relief hole once the explosion, equipment, personnel from harm; equipment no dead ends, lighter, faster loading and unloading, rinse, meet the GMP standard.
How to properly operate the boiling dryer?
1 boiling dryer pre-production preparations
1.1 check production tools are complete, clean, boiling drier parts installation intact.
1.2 Check steam, compressed air supply to normal.
1.3 check the feed materials are complete, the number, name, batch number is consistent with the instructions for the production, the appearance of eligibility.
Boiling dryer operation:
2.1 ON boiling dryer power control box to open the compressed air valve to adjust the gas pressure (0.5 to 0.6 MPa).
Set the inlet air temperature (press 3 seconds to set the key, and then press the plus 2.2 if necessary, to subtrahend key to the desired temperature, press 3 seconds set last key temperature settings).
After 2.3 good system particles into the hopper, the hopper is pushed into the casing, be seated correctly hopper before being pushed into the pneumatic switch, the upper and lower airbags into a 0.1 to 0.15 MPa compressed air so that the hopper up and down in a sealed state.
2.4 open plus hot air out of the manual shut-off valve.
By the induced draft fan start button, start to be fan after stirring press the start key mixing operation, dry start.
The 2.6 inlet air temperature slowly rose through the automatic control system about the set temperature, the wind to be a rise in temperature to about 60 ℃, the material is about to dry.
2.7 particles uneven drying process, you must stop the drying hopper turn grain pull out, again and again into the drying.
2.8 Sampling determination of whether the particles of water to meet the requirements.
2.9 particles reach the requirements of the degree of drying, pull out the cold door switch, with clean, cold air cooling material a few minutes.
Stop key 2.10 according to the fan, the fan and stirring at the same time stop (electrical chain), push and pull the trap bag lifting cylinder several times, so that the the plot material on the bag to shake into the hopper.
2.11 Pull out the inflatable switch until the airbag seals deflated restored before the hopper out.
3 Close boiling dryer control box power and steam source, compressed air source.
Production after clearance clearance standards. Clear the scene finished, hang up the "cleared" state license.
Fill equipment operating records.
How the boiling dryer repair and maintenance?
1, the boiling of the day-to-day maintenance of the dryer
1.1 boiling dryer operator before each operation to check the steam valve, compressed air and the normal range table.
1.2 Check air bag seals whether raised, flat head screw is loose and to prevent cars expected is pushed crashed.
1.3 check the hopper blade turbine is too tight, tight vanes coupled with the resistance of the material, resulting in the stirring motor drive load increases, the the broken transmission bumps or motor burned.
1.4 check on whether the air pressure under the airbag ring below 0.1 ~ 0.15mpa high pressure likely to cause sealing burst too low will not achieve the sealing action of the powder leakage, affect the production efficiency and dry mass.
1.5 Check the compressed air pressure is too high:
1.5.1 is likely to cause the hot and cold damper cylinder momentum Ambassador damper live then broken or damage to the sealant, leak affect the drying effect.
1.5.2 bag Guijia cylinder thrust is too large, the plunger to be easily bent.
2, boiling dryer regular maintenance
2.1 regularly cleaned once a month in efficiency filter bags from boiling dryer vents enter the loose framework screws, remove the mesh bag to use detergent soak for 30 minutes, then rinse with water, drying.
2.2 regularly cleaning lubricating the gearbox boiling dryer stirring device.
2.3 regular plus the boiling dryer cars expected transmission gear lubricants, to fill equipment lubrication record. |
